Algeria Adds 200,000 m3/day of Increased Seawater Desalination Capacity

SAN LEANDRO, Calif.--(BUSINESS WIRE)--Sept. 24, 2008--Energy Recovery, Inc. ("ERI") (NASDAQ:ERII), a global leader of ultra-high-efficiency energy recovery products and technology for desalination, announced that it had won another large-scale energy recovery contract for seawater reverse osmosis (SWRO) desalination in Algeria. The Mostaganem SWRO Desalination Plant, located approximately 38 miles east of Oran in the western seaside region of the country, will have a total capacity of 200,000 cubic meters per day (m3/day) (52.8 million US gallons per day), enough to supply drinking water to a population of over one million people. The plant is expected to begin operation sometime in the second half of 2009.

The Mostaganem plant is being built on a 25-year build own operate and transfer basis by UTE Mostaganem, a consortium consisting of Inima (Grupo OHL) and Aqualia (Grupo FCC) of Spain. Inima previously selected ERI to provide its advanced energy-saving PX technology for both the 16,000 m3/day Los Cabos and 65,000 m3/day Alicante desalination plants. The Mostaganem project is one of many for ERI in the region, including the 200,000 m3/day Hamma plant built by GE Water and the 200,000 m3/day Beni Saf and 100,000 m3/day Skikda plants currently being built by GEIDA.

The process for the Mostaganem plant will include 240 ERI PX-220 Pressure Exchanger devices arranged in 16 trains of 15 units each. Utilizing PX technology will help significantly reduce power consumption by the plant's high-pressure pumps. Each device will save approximately 80 kilowatts for a total plant energy savings of over 19 mega watts.

Rick Stover, ERI's Chief Technical Officer and Vice President of Sales said, "with this contract, ERI increases its project wins in Algeria to 1,220,000 m3/day of permeate capacity. We are proud to be the energy recovery solution for the region."
